Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00060 | $0.01903 |
| Opus 5.5 | $0.00024 | $0.00761 |
| Sonnet 5.5 | $0.00012 | $0.00381 |
| Haiku 4.5 | $0.00006 | $0.00190 |
Grade A, and why
playwright-e2e-tester scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Playwright E2E Tester
Overview
Expert in end-to-end testing with Playwright, the modern cross-browser testing framework. Specializes in test generation, page object patterns, visual regression testing, and CI/CD integration. Handles complex testing scenarios including authentication flows, API mocking, and mobile emulation.
When to Use
- Setting up Playwright in a new or existing project
- Writing E2E tests for critical user flows
- Debugging flaky tests or test failures
- Implementing visual regression testing
- Configuring Playwright for CI/CD pipelines
- Migrating from Cypress, Selenium, or Puppeteer
- Testing authenticated flows with session management
- Cross-browser testing (Chromium, Firefox, WebKit)
Capabilities
Test Generation & Writing
- Generate Playwright tests from user stories or acceptance criteria
- Write tests using best practices (locators, assertions, waits)
- Implement Page Object Model (POM) patterns
- Create reusable test fixtures and utilities
- Handle dynamic content and race conditions
Configuration & Setup
- Configure
playwright.config.tsfor different environments - Set up projects for multiple browsers and viewports
- Configure base URL, timeouts, and retries
- Implement global setup/teardown for auth
- Set up test reporters (HTML, JSON, JUnit)
Advanced Patterns
- API mocking with
route()andfulfill() - Network interception and request validation
- Visual regression with
toHaveScreenshot() - Accessibility testing with
@axe-core/playwright - Mobile emulation and device testing
- Geolocation and permissions mocking
CI/CD Integration
- GitHub Actions workflow configuration
- Parallel test execution with sharding
- Artifact collection (traces, screenshots, videos)
- Flaky test detection and retry strategies
- Test result reporting and notifications
Debugging & Maintenance
- Use Playwright Inspector and Trace Viewer
- Debug with
page.pause()and headed mode - Analyze test traces for failures
- Reduce test flakiness with proper waits
- Maintain test stability over time
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 1mo ago First seen · 250 lines · 60 tokens per session scan A bd4e279b764f
playwright-e2e-tester is a skill published in the GitHub repository curiositech/some_claude_skills (253 stars, last pushed 1mo ago), licensed MIT. It adds 60 tokens to every session and 1,903 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
